The one great advantage of Bhakti is that it is the easiest and most natural way to reach the great divine end in view; it's great disadvantage is that in its lower forms it oftentimes degenerates into hideous fanaticism. The fanatical crew in Hinduism, Mohammedanism, or Christianity, have always been almost exclusively recruited from these worshippers  on the lower planes of Bhakti. That singleness of attachment (Nishthâ) to a loved object, without which no genuine love can grow, is very often also the cause of the denunciation of everything else. All the weak and undeveloped minds in every religion or country have only one way of loving their own ideal, i.e., by hating every other ideal. Herein is the explanation of why the same man who is so lovingly attached to his own ideal of God, so devoted to his own ideal of religion, becomes a howling fanatic as soon as he sees or hears anything of any other ideal.
Give up the idea that by ruling over others you can do any good to them. But you can do just as much as you can in the case of the plant: you can supply the growing seed with the materials for the making up of its body, bringing to it the earth, the water, the air, that it wants. It will take all that it wants by its own nature, it will assimilate and grow by its own nature.
The tender plant of spirituality will die if exposed too early to the action of a constant change of ideas and ideals. Many people, in the name of what may be called religious liberalism, may be seen feeding their idle curiosity with a continuous succession of different ideals. With them, hearing new things grows into a kind of disease, a sort of religious drink-mania. They want to hear new things just by way of getting a temporary nervous excitement, and when one such exciting influence has had its effect on them, they are ready for another. Religion is with these people a sort of intellectual opium-eating, and there it ends.
We must also remember that in every little village-god and every little superstitious custom is that which we are accustomed to call our religious faith. But local customs are infinite and contradictory. Which are we to obey, and which not to obey? The Br?hmin of Southern India, for instance, would shrink in horror at the sight of another Brahmin eating meat; a Brahmin in the North thinks it a most glorious and holy thing to do he kills goats by the hundred in sacrifice. If you put forward your custom, they are equally ready with theirs. Various are the customs all over India, but they are local. The greatest mistake made is that ignorant people always think that this local custom is the essence of our religion.
